To begin with, and to work more comfortably, we will remove the straps from the smartwatch.

We remove the four Torx screws (T3) that hold the casing, and with the help of a flat tool we will unhook the casing, and once unhooked we must disconnect the flex that connects it to the motherboard.

We disconnect the flex from the motherboard and the one from the side buttons that are connected to the auxiliary plate, and with the help of some tweezers we will remove the plate.

We remove the shield that covers the screen connectors, and we will remove the three Phillips screws (PH # 00) that hold the motherboard, and with the help of a flat tool we will remove it from the screen chassis.

Finally, we will only have to take off and unhook the flex from the damaged side buttons that we have to change.
